Danish-speaking users were recently hit by malware spread through Dropbox. The messages claimed to provide shipping details and an invoice, but the attached file was actually a .zip archive that contained a JavaScript file with Trojan dropper in it. These emails were sent out for about 12 hours. Luckily, Dropbox responded quickly, with many of the links were disabled in about an hour.

The attack hit Denmark, Germany and several surrounding countries through a language-based list of email addresses. Dropbox is an attractive avenue for malware because it is a popular service, and because email providers are increasingly putting stringent limits on the kinds of files that can be sent as attachments.

Despite these security concerns, cloud storage remains one of the more convenient ways to store some of your data today. So what can businesses do to prevent cyber attacks through these cloud-based storage solutions? Aside from using spam filters and anti-virus tools and training employees to recognize malicious emails before making a damaging click, organizations can ban inbound Dropbox content links. Or, you could tweak your company’s spam filter or the web filter to block access to Dropbox entirely.

Keeping data secure is also the responsibility of the consumer. Poor password security can give cyber criminals an all-access pass to your private data. Avoid using the same password over multiple platforms — add letters, numbers and symbols to your password. Don’t use a password that’s related to your personal life.

Cloud-based storage solutions will continue to grow and evolve, so it’s important to be aware of the security challenges of storing precious memories and important documents in the cloud.
